RICHARD P. SECKENDORI, OF' SOMERVILLE; 'MASSACHUSETTS, ASSIGNOR TO THE CAMBRIDGE PAPERBOX (10., OF CAMBRIDGE, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS Application filed June 29,

known as paper boxes, wherein the walls comprise a foundation of paper stock'or other suitable material which is covered with paper or its equivalent.

My invention is addressed more particularly to the problem of covering boxes of octagonal or other shape that present oblique walls to be covered.

Practicable machines for covering rectangular boxes have long been known'in' the art, but prior tomy invention, so far as I am aware, there has been no practicable machine that would cover boxes presenting oblique side walls. My invention will best be understood from a description of an illustrative embodiment thereof, shown in the accompanying drawings.

. The machine frame 1, of suitable shape and MACHINE FOR COVERING BOXES 1929'. Serial No. 374,871.

construction to carry the various parts, is

provided, see Fig. 1, with bearings for a drive shaft 2, upon. which is loosely mounted a belt pplley 3. This belt pulley constitutes one mem er of a friction clutch, the other member of which-is a conical disk 4 splined upon the shaft 2, and normally pressed by a spring .5 into frictional driving contactwith thebelt pulley 3. To withdraw the friction disk from driving contact with the pulley, said disk is provided: at one side the shaft with a clutch rod 6 mounted to slide longitudinally in a direction parallel with said drive shaft, said clutch rodbeing in turn controlled by a bell crank lever 7 fulcrumed at 8 on the frame. The horizontal. arm of said bell crank lever receives aslide pin 9 mounted in a block jointed to'the upper .end of an arm 10 rising from a horizontal shaft 11 fulcirumed in brackets upon the frame, and 'inturn. provided with a suitable treadle lever 12.

Normally the clutch spring 5 presses the clutch diskto the right into engaging contact with'the pulley 3 against the, weight and resistance of the several levers described, but

said disk may be withdrawn from contact with its driving pulley by depression of the horizontal arm of the bell crank lever 7 whlch, see Fig. 2, is accomplishedby a segmental cam 13 secured upon the barrel cam '14 fast upon the vertical camshaft 15 mounted in bearings in the frame. Rotation of the barrel cam l l'causes the inclined leading edge of-the segment 13 to depress the pin 9, Fig. 1,

which underlies it, andthereby to depress the horizontal arm of the bell crank ,7, and through the operating rod 6 withdraw the clutch disk from operating contact with the pulley 3 and arrestrotation of the main shaft and cam shaft referred to. To release the clutch, the foot treadle 12 is depressed, thereby through the shaft 11 and upright arm 10 to withdraw the pin 9 longitudinally from pressed by a spring surrounding it which is not shown, springs against the side of said segmental cam 13 and remains so pressed until said cam shall have been rotated past it, whereupon said pin is further pressed inward into the path of said cam, so as to be engaged by its inclined leading end toward the close of a complete rotation and again depressed to arrest the driving movement as before. Thus the construction is such that when once the foot treadle is touched, it releases the machine for a single complete rotati on of the drive shaft, whereupon said shaft is automatically stopped until said treadle is again depressed to release it.

By retaining the foot pedal depressed, the machine will continue without interruption for a succession of turns or cycles, and this is frequently done when the work is such or the skill of the operator such as to make it practicable.

The vertical cam shaft 15 is driven from the main or clutch shaft through a worm wheel 16 thereon, Fig. 2, and a worm 17, Fig. 1, on the clutch shaft.

Upon the upper end of the cam shaft 15, see Fig. 1, is mounted a barrel cam 18, containing two cam paths 19 and 20. The cam 19 receives a roller stud 21 upon the side of a lever 22 fulcrumed at 23 in an arm of a bracket 24 on the frame, and is provided at its short end with a weight 25 to aid in balancing and taking up slack in the motion.

At its opposite or free end, said lever 22 is provided with a roller stud 26, which may be clamped in adjusted position by a clamping device 27 in the slotted end of a link 28.

This link is jointed at its upper end at 29 to a vertical slide bar 30 mounted to slide in hearings or ways 31 in the arm 32 of the bracket 24 referred to.

At its lower end saidslide bar 30 is provided with a cylindrical extension 33 carrying at its lower end, see Fig. 7, the lower member 34 of a two-part presser, the other part 35 of which rests normally uponand effectively as a part of it.

The upper presser member 35, Fig. 7 is secured to a cross-head 36 which, see Fig. 1, is carried by and upon the lower ends of two parallel slide rods 37.

These slide rods are mounted to slide at their lower ends in a head 38 secured to the lower end of the slide bar 30, also in bearings in said arm 32, and at their upper ends are connected by a cross-head 38.

The top'cross-hea-d 38' connecting the slide rods 37, see Fig; 1, is connected by a spring 39 with said slide bar 30, so that while said slide rods and the heads connecting the same are free to move with the slide bar 30 as the latter is moved vertically by the lever 22, said slide rods are permitted a movement independent of said slide bar, under conditions 7 that will be hereinafter described.

During a certain part of the vertical move ment of the two-part presser 34, 35, said parts move as a unit, but at times they are separated, and this separation is controlled by said spring 39, which brings the two parts together again at the appropriate time.

The bracket arm 32 also has bearings for two additional slide rods 40 which, at their lower ends, see Fig. 1, are connected by a horizontal yoke 41, made u shape to span the slide bar 30 and slide rods 37 already described. This U-sliaped yoke 41 carries in its arms the oppositely extended bars 42, upon which are adj ustably mounted the heads 43, in which are adj ustably held the short vertical rods 44. These rods 44 have secured to their upper ends the ejectors 45, which depend through both presser members 34, 35. While normally they remain in position concealed within said presser members or one of them, at times these ejectors may be projected downward to eject or remove from the presser the completed covered box that may be carried thereon as the latter are elevated at completion of the covering operation. This will be later described more in detail.

The ejector carrying yoke 41 is actuated by a link 46, shown mainly in dotted lines, Fig. 1. which is jointed at its upper end to a lever 47 fulcrumed at 48 on an arm of the bracket 24, and provided at its opposite end with a roller stud 49 which travels in a path cam 20 heretofore referred to, in the barrel 18.

Said path cams are so shaped as to give to their respective levers and the parts controlled thereby the necessary movements to be hereinafter described in detail.

Beneath the presser, see Fig. 1, stands the yielding platen 5O faced with a felt or other suitable covering 51, which platen is mount ed upon the upper end of a tubular column 52. Standing within and carrying this column is a telescoping support 53, the latter seated upon the base of the machine and containing a spring 54 which extends upward within and to carry the upper telescoping member 52, and through the latter the platen column 52. Upward spring pressed movement of the member 53 and the platen carried thereon is limited by a collar 55, Fig. 1, which seats against the under side of the base portion of a bracket 56 mounted in the frame.

The box B and the paper blank P that is to be used to cover it are fitted upon the elevated presser as indicated in Fig. 1 and, during the subsequent downward movement of the presser, are clamped between the latter and the spring supported platen 50, which latter yields before the descending presser to permit the latter to carry the box and blank into one or another of its successive depressed positions, as will be more fully hereinafter described.

Before describing the wiper mechanism,

reference should be made to Figs. 5 and 6,

assumes where are. shown the octagonal boxBgherein used as an example of a box or cover having oblique walls, 1 and "the paper or other blank P which is who usedfor covering the box.

The blankis coated at its inner top surface with an adhesiveand is applied to the box as shown."

It will be observed that the boxcomprises the pairs of parallel end walls I), 1), parallel side walls I), b, and the pairs of :oblique walls 6 6 The bottom of the boxis indicated at 6 v r The paper or other cover blank P comprises a central portion p Fig. 7 ,from which radiate the pairs of flaps p, p, and p, p, Fig.5, and the pairs of oblique flaps 2 p Itwill be observed that the opposite flaps p, p, are provided at their side edges with wing portion p, p, their edges-tapering gradually inward from their respective ends to the points 17 below which they taper more abruptly to the actual bases of the flaps. The oblique flaps p are provided with wings p? at one of their side edges only, the edges of said wings taperinginwardly toward'their bases as do the Wings 12, and having the same breaks at p below which the taper is more accentuated, while the remaining flaps p have their side edges tapered inwardly as at p from the basesthereof to their extremities.

The problem is to wipe or upturn the several flaps against the side walls of thebox or its equivalent, and to overlap the edgesthereof at the corners where the side walls meet, and then to. inturn'the free ends of the upturned flaps over and downward against the inner faces of the box walls.

'This is accomplished by first upturning the opposite broadened flaps p, p, against the corresponding Walls 6, b, of the box, as indicated in Fig. 7, and thenbending the wings pf of each flap-around and against the corresponding, portions of the adjacent oblique walls of the box; next the pairs of oblique flaps p, 12 are similarly wiped upward against the oblique walls b of the box, and with their straight inwardly tapering edges overlying the previously inwardly bent wing portions 72 0f the previously folded flaps p,

- and with their single wings p. wiped around and bentagainst the adjacent portions'of the walls 6, b of the box; and finally the inupper edges above the rim of the boxand wardly tapering or narrowing straightedged fiaps'p, 71 are folded upward against the side walls 6 b ofthe box, and against p the bent-over wings p of the oblique flaps 71 Thus all the side walls of the box will be perfectly covered with the edges covered by the wing portions of such flaps as are provided with the same. b

These upturnedflaps will project at their remain to be pressed inward toward the center of the box and downward against the frame.

are to be performed :by the mechanism that 1 will nowbe described.

Referring toF-igs. 4 and 7, at the level of the platen when the latter :is in its elevated position, opposite the two side walls of the platen that receive the side walls I), b, of the box to be covered, are two wiper brushes 57, which are shown.as'comprising'respectively a plurality of small bunches of bristles arranged in horizontal series; to constitute in effect a single brush of the length of the series, said wiper brushes standing directly below theflaps of the blank that are to be upturned against thebox walls at the H10- ment said blank, with its box, gripped between the presser and the platen, begin their descent at the center of the machine.

t The brushes 5'? are mounted in suitable These pins 62arecarried in the ends of arms 63 slotted at their oppositeends at 64rto receive the clamping screws 65, by which said arms are 'adjustably secured to the adjustable but stationary heads (id-mounted upon the These heads are slotted at 67 to receive the clamping screws-68 onthe frame, which permit theheads to bemoved to and from the platen to accommodate boxes of different sizes.

As the presser is depressed by its cam, carrying before it the platen'with the box and covering blank gripped between them, the stationary wiper brushes 57, see Fig. .7, will engage the extended flaps p, p, and wipe them upward into their dotted line positions close against the-outer faces of thewalls b, b, of the box,.to which said flaps, having been previously pasted, adhere instantly upon 'makjing contact therewith. I I

The brush holders 58 remain rigid against the wiping action as the flaps are wiped up- ,wardagainst the box walls, but are free to turn freely upward about their hinges-59 during the'subsequent ascent of the platen with the covered box thereon, to avoid undue scraping or frictional contact with the paper covered .box walls. v

The action described "has upturned the flaps p, p, as in Fig. 6, but the Wing portions p remain projecting. beyond the oblique walls [2 as in Fig.6, and must be inturned against said oblique walls before the oblique flaps can be upturned against their corresponding-oblique box walls.

Toaccomplishthis inturning of the Wings 3), I have rovided, see Fig. 8, a air of J wing wipers69, shown as verticalplatescorrugated at their inner faces, as at 70, and

arranged ata level slightly below the level of the brush wipers 57, aswill best appear from dotted lines, Fig. 7. l

" Each wing wiper 69 is made vertically adjustable at 71, Fig. 9, in a head 72 fast on the end of one of the horizontal carrying rods 73. This carrying rod 7 3 is longitudinally adjustable in thehead 74 on the vertical rod 75, which in turn is vertically adjustable in the head 76. The head 76 is hinged about a vertical pivot 77, Fig. 9, in another head 78 adjustable on and along the horizontal squared bar 79. This horizontal squared bar 79, see Fig. 7, is carried by a yoke 80 on two horizontal slide rods 81 mounted in lugs 82 on the head 66 already referred to as adjustably mounted in the frame.

By means of the adjustments described, the heads 66 upon opposite sides of thebox may be brought toward or from each other to accommodate varying dimensions of box in that direction, and the heads on the sides of the box may also be adjusted out-ward or from each other to accommodate different dimensions of the box in that direction.

In whatever properly adjusted position they may have been set, as the box with its covering flaps p, p, upturned as in Fig. 7 is depressed by and between the presser and platen, seeFig. 8, the projecting flap wings 72* will be depressed between the stationary wipers 69 described, which latter will inturn said Wings 17 against the adjacent portions of the oblique walls of the box, to'which said wings will adhere.

The wing wipers 69 just described, see Fig. 8, first meet the descending narrow neck portions of the blank flaps p, 19, close to the points at which they join the central portion of the covering blank, so as to wipe said narrow wing portions against the oblique walls of the box. By thus engaging the narrow portions of the wings near the bases of said flaps, the entire flaps are swung around into what as a rule will be suitable firm contact with the oblique box walls but, to make certain that the wider portions of said wings are firmly and smoothly pressed against said oblique box walls, it is desirable that in the further descent of the box and cover flaps, said wing wipers be moved inward to cause their wipers to act upon the entire areas of the wider portions of said wings. The. mounting of the wing wiper carrying heads 76 upon the vertical pivots 77 permit said wipers to spread as they are pushed inward to reach and smooth the widest portions of the covering wings, they being held yieldingly in contact with said wings during the smoothing operation by the coil springs 85, see Fig, 9, surrounding the pivot 77. These springs serve also to return the wipers to their normal positions, Fig. 8, when they are withdrawn from the spreading oblique walls of the box.

To move said wing wipers bodily inward thus to cause them to spread and smooth the covering wings'uponthe oblique box walls,

the'squared rods 79, Figs. 8 to 10 inclusive, are moved bodily inward at the proper times, carrying with them the heads and wing wipers described by the following mechanism:

' Referring to Figs. 2 and 3, the horizontal: slide rods 81 are connected at opposite sides of the machine by a cross bar 88 held in ad justed position upon said slide rods, between the collars 84 fastened upon the guide rods by clamping screws 85. At an intermediate point on said cross bar 83 is jointed at 87 a link 88, which at its opposite end is jointed at 89 to an arm 90 fast on a horizontal shaft 91 mounted in the frame of the machine.

The shafts 91 at opposite sides of the ma-;- chine are provided respectively with depending arms 92, provided with pins 93, to which are jointed the ends of the connecting rods 94 jointed at their opposite ends at 95 to the opposite ends of a T-shaped lever 96""85 fulcrumed upon a stud 97 on the frame. The depending arms 92 on the shaft 91 described are provided with a plurality of holes atdif'ferent radial distances from the shafts '91, into which the pins 93 may be placed toi'te 95 by which to vary the longitudinal throw-' of the connecting rods by and from given oscillations of said lever 96.

The horizontal or intermediate arm of the T-shaped lever 96, which is marked 98, carries at its free end a roller stud 99, which enters a cam groove 100 in the barrel cam 14 previously described.

Rotation of the cam shaft 15 will thus oscillate the T-shaped lever 96, and through the connections described will cause the wing wipers 69, Fig. 8, at the proper times to ad vance inwardly to cause the wing wipers to smooth the wing flaps 7* against the spreading oblique side walls of the box. Thus as the box descends, these spreading wings are wiped smoothly upon the oblique box walls by a wiping action beginning at the bottom and close to the angle where they are bent around the corner of the box, and extending upward and further inward by a natural wiping action, such as would'be performed if said wings were turned and smoothed by hand.

The next step, as stated, is to upturn the oblique flaps 39 against the obliquely standing box'walls 6 with their straight tapering edges overlying the overturned wing portions of the previously folded flaps p.

This is accomplished in the further descent of the presser and platen with the box and covering blank still firmly gripped between them. Referring to Figs. 4, 9 and 11 to 13 inclusive, I have provided at the next level below the wing wipers 69 described, obliquely positioned stationary brush wipers reac es 101. These brushes are clamped in holders 102 horizontally pivoted at 103,'see Fig. 11,

in heads 104 adjustably secured to .thedown-' turned lower ends of the holding rods 105, see Fig. 13. These holding rods 105 are adjustably mounted in blocks 106, see Fig. 11, on the upper ends of the short rods 107.

There are two of thesevertical rods 107 at each side .of theniachine, holding respectively the oblique wiper brushes at that side of the machine, and said pairs of rods, see Fig. 4, are respectively, adjustably mounted in the ends .of arms 10.8 on adjustableheads 66 heretofore referred to.

Referring to Fig. 4, it will be seen that by rotatively and slidinglyadjusting the brush carrying heads and rods, one relative to another, the oblique wiper brushes 101 may be given :any desired obliquity inany desired position and at any desired level, properly to act upon the oblique flaps and box walls To turn these wings inward against the adjacent portions of the box walls, I have provided wing wipers 111, shown best in Figs. 10 and .14, which act similarly to the action of the wing wipers -69 heretofore de scribed. r k Each of said'wing wipers 111 is adjustably mounted in the block 112 on theend of the, horizontal rod 113 adjustably mounted in the head 11 1 on the lower end of vertical rod 115.

horizontal rod 117 adjustably secured in a lug on the swinging head 76 heretofore described as carrying the wing wiper 69.

WVhen once these wing wipers 111 are properly adjusted to the box and blank to be acted upon, they will operatein the further descent of the box and covering blank to engage the oblique flap wings 79 and turn them against and smooth them upon the adjacent side walls of the box, precisely as did the wing wipers 69 referred to.

The same inward or closing movement of the squared shafts 7,9 that carried the wing I wipers 69 inward against the flap wings 12 is continued to carry the wing wipers l11.at

the lower level into engagement with the wings p towipe them around the box corners, but the wiper heads 76, after having spread to permit the inwardly-closing wiper 69 to perform their work, :are freedjby the This vertical rod 115 is adjustably secured in the block 116 on the end of the descending boxto spring back to their original positions before theyare a second time turned to permit thespreading of the wing wipers 111 in the subsequent turning an wiping of the wings p, the stationary, oblique wiper brushes performing their work between the times ofoperation of the wing" I wipers 69 and the wing wipers 111. In prac tiee the action is speeded up somewhat by causing the stationary oblique brush wipers 101 to begin their work before the wing wi ers 69 have completed their work, and t e wving ipers 111 may begin to function before the wiper brushes 101 have completed their work. This capacity for one operation to overlap another is particularly useful in handling deep boxes.

In thefurther descentof the presser and platen with the box and covering blank gripped between them, the latter meet the final stationary brush wipers shown in Fig. 15 and marked 118. wipers, like those previously described, is mounted in .a head 119 horizontally pivoted at .120 to a block 121 ,adjustably mounted upon the upright pinl22. Each. pin 122,.

see Fig. 4, is carried in the end of anarml23 slotted at 124- to receive the clamp .screw 125, by p which said arm is adj ustably mounted upon the bracket 126. This bracket 126, see Fig. 1 is adj ustably mounted upon the frame of the machine and is adjustable inward and outward thereon by the clamping device 127. One of theserbrackets and its, aecompanyin brush wiper is mounted in the frame .at'eac side of't he box, that is to say, the two are mounted at-opposite sides .of the machine, as

bestappears in ig. 14. V v As the brush .and its blank are carried downward between :these two final jbrush wipers, the latter engage the two remaining unfolded .flaps p and fold the latter .npward and against the remaining two .sides of the box, as best appears from'Fig. 15.

Since the last two-flaps thatare upturned have straight inwardly tapering, side edges with nooverlappmg wings to be handled,

thereis no occasion for subsequently acting wingwipers.

a All ,the'covering flaps have now been upturned against the side walls of the box and Each of these "brush stand with their upturned edges extending I substantially above the rim of :the box walls and above the presser, as shown in Figs. .13 and 15. v s

In the operation of the machine, the

presser. and platen continuetheir descent with the boxits walls now-.covered,still firmly clamped between them, below the positions shown in Fi 15, for the 'purposeof'inturningthe'flapsabout the rimofthebox wall.

In this-further operation of the machine, the two members of the presser no'longer,

move .asa unit; the lower member 34,actuated by the bar 33, continues its descent push- 9 ing before it the platen with the box still gripped between them, but the upper presser member 35 is arrested as illustrated in the detail, Fig. 16. The upper presser member, as stated, see Fig. 1, is secured to the lower ends of the parallel rods 37, which are connected at their upper ends by the cross-head 38", from the back of which depends a stop ired 38:, shown in dotted lines, Fi 1. As the 1 presser bar 33 continues through the final portion of its descent as described, the stop rod 38* meets the top of the now stationary lever 47, which prevents further descent of the up- ;per presser member, causing the further de scent of the lower presser member to open up the space between the upper and lower presser members, as shown in Fig. 16. At the same time the spring 39, Fig. 1, is put under tension, for the purpose of causing the upper presser member to follow and overtake the lower presser member when the former is released for that purpose.

By the time the lower presser member 34 has reached its lowest position, as-shown in 2 Fig. 16, a suflicient space has been opened up between the two presser members to permit the upstanding ends of the covering flaps to be folded inward over the rim of the box wall, as shown in- Fig. 17, whereupon said lever 47, 3 Fig. 1, is depressed by its cam to permit said spring 39 to pull the cross head 38 and the upper presser member depending therefrom downward to overtake and close upon the 7: lower presser member, and in so doing to bend downward before it the horizontal mturned ends of the covering flaps and place the latter against the inner faces of the box wall, as shown in Fig. 18. Before the upstanding ends of the covering fiaps'are turned inward, 10 as described, and of course before the upper presser member descends to close the folding space, as described, it isdesirable to straighten up the box walls accurately into 5 desired alignment, according to the desired shape of the box. Since the presser is given the desired outline ofthe box and is accurately made to the dimensions desired for the interior of the box, this straightening of the side walls is conveniently obtained by pressing 3150' said walls firmly against the side walls or edge of the presser. For clearness, in Figs. 16 to 18, the paper covering is shown of exaggerated thlckness, which results in a clearance between the lower presser member and the box wall, which would not appear in practice.

To accomplish this, see Fig. 7 I have provided side wall pressers 128, which are of a size and shape to fit the side walls 6 of the s box and the adjacent oblique walls 6 at each side of the box. Each side wall presser 128 is lined with felt or other suitable material 129, and atits outer face is provided with a rib 130 which is received in a socket 131 and is there clamped by one or more set screws 132. The socket 131 is yieldingly carried by and between two rods 133 mounted to slide in the frame brackets 66, as is usual in machines of this character.

Mounted in suitablebearings also in said brackets 66 is a horizontal shaft 134, Fig. 7,

upon which is mounted an oscillatory arm 135, which is provided at its hub with two cam projections 136, 137, adapted respectively to engage a lug shown as spanned by them and mounted upon the presser head 131.

When the head 135 is oscillated to the right, Fig. 7 the cam 136 will engage the lug referred to, and will push the presser member 128 to the right a sufficient distance to straighten up the box sides preparatory to infolding of the ends of the flaps above the same. Upon the return oscillation of said member 135 in the opposite direction, said piesser member will be released and will spring back to its position shown in Fig. 7, and will immediately thereafter be engaged by the cam lug 137, which is a little higher than thelug 136, and will be again moved to the right and through a slightly greater distance than before, to compress the covering upon the outer and inner faces of the box wall, as will be more fully described presently.

It is to be understood that the presser means just described is reproduced at all four sides of the machine, to operate upon the opposite sides of the box.

Practically simultaneously with the first movement of the presser 128 described for straightening up the box sides, the upstanding ends of the covering flaps will be wiped inward to a horizontal position in the space between the separated upper and lower pres ser members. This is accomplished by horizontal, inwardly moving wiper plates or wipers 138, one at each side of the box, that is to say, one above and operating in conjunction with each of the pressers 128.

Each wiper 138 is clamped in a cross head 139 mounted upon the ends of horizontal slide rods 140 carried in bearings upon the bracket arms 66.

Between the slide rods 140 the cross head 139 is connected by a link 141 with the oscillatory head 135, so that as said head is oscillated to cause its earn 136 to im part wall straightening movement to the presser 128, said, head through the link 141 will simultaneously push the wiper 138 inward to fold the upstanding end of the covering flap that stands in front of it inward and downward into a horizontal position overlying the lower presser member 34 then in its lowermost position, as shown in Fig. 17.

lever 47, Fig. 1, that had supported it and,

time

actuated by the spring 39, will follow the" turned covering flap ends and turn them.

downward and outward against the inner faces of theupper, p ortions of the straightened box walls, as shown in Fig. 18. This final downward movement of the upper presser member 35 takes place during the first partof the withdrawal movement of the presser 128 and Wiper 138 and, with said presser member still in its lowermost position, the continued return oscillatory movement of the head 135 for further withdrawal of the presser 1'28 and wiper 138, will cause the lower and higher cam 137 on said oscillatory head to engage the lug on the presser head and push the latter a second time inward. and

farther than before, to press thenowfu'lly' covered box wall tightly againstthe upper and lower presser members within, to smooth out and finally set the covering upon the box wall.

Referring to Fig. 7, each oscillatory head 135 is actuated by a link 142 from a vertically sliding bar 143 mounted ina bearing in said bracket arm 66. Said slide bar 143 is socketed at its lower endto receive the end of the horizontal arm 144, to which said head is adj ustably secured by a clamp 145.

There are four of these horizontal arms 144, the same radiating from a common head 146, Fig. 1, mounted to reciprocate vertically upon a tubular support 147 resting upon: the

frame or more strictly upon the face of the bra'cl'ret 56 which is carried by the frame.

The platen supported column 52 slides within this tubular support 147. Said head 146 is raised and lowered by a link 148, Fig. 1, connected with one end of a lever 149 fulcrumed at 150 in said bracket arm 56, and carrying at its opposite end a roller stud 151 which enters a cam groove 152 in the-barrel cam 14earlier described. 7

WVhen said cam is rotated by the cam shaft 15 to cause the various motions to function, said lever 149 is oscillated at the proper times to raise and lower the head 146, and its four rotating arms 144, to cause the box wall pressers and final infolding wipers to function as described.

After the upturned flap endshave been inturnedbetween the presser members and downturned by the closing of the upper presser memberwithin the box down upon the lower presser member, and the accompanying pressing of the covered walls tightly against the presser edges, the presser rises with its members still closed upon each other within the covered box, the spring supported platen following it still holding the covered box clamped tightly between it and the press er until the latter reaches its" most elevated ositio'n, Fig. 1, limited by the collar 55, Fig.

1, below thesliding-head 146, at-or about which time the. now covered box in its further rising movement. meets the lower ends of the ejector rods 45,v Fig. 1, which, meanwhile, have been lowered into proper position, so that the continued elevating movement of the presser will cause the latter to be lifted out:

from and-clear of the covered box. The box wiilbe held upon the platen by and against the ej'ectors until the presser has cleared it, whenthe box is thrown out to one side preparatory to introduction of a new box having a new covering blank adhering thereto for a repetition of the covering movement heretoforedescribed;

This final ejectingor throwing out of the covered boxto makeway for a new box to be covered'is, accomplished, see Fig. 1, by a horizontal throw-out rod 153 mounted to slide in the frame arm 24 and actuated by a spring 154. Said rod 153' is moved tothe right, Fig. 1, to compress its spring by an arm 155 carrying a roller stud 156acted upon by a horizontal cam 57 onthe .cam shaft 15. In the rotation of said shaft 15, 7 said rod 153 is moved gradually to the right to compress. its spring and, at the appropriate time, after the covered box has been freed as described from its contained presser, said cam releases the roller stud 156 and permits the spring 154 to impart a quick throwout movement of the rod 153, to the left, Fig. 1, to cast the box out of the machine into a suitable receptacle provided therefor. p 5

To summarize the steps in the covering of a box in pursuance of my invention, assuming the parts to be in their positions, Fig. 1, the operatortakes a box blank such as shown in Fig. 5, with the pasted blank previously applied to the bottom thereof and-adhering with substantialcontinuity throughout its middle portion to the bottom of the box, and places or fits the same from beneathupon the elevated two-part presser, the parts of the presser being closed one against the other, as indicated.

The presser now descends until the box ,with its adhering covering blank meets the ary wiper brushes 57 ,F ig; 7 to engage the horizontally projecting flaps p, p, and turn them upwardagainst the corresponding box walls. Immediately thereafter in the further descent of the presser and platen, the wing wipers 69, Fig. 8, already moving'or about to move, inward, engage the wing portions p of the coverin g'flaps p, ,p, and turn the Wings 12 p against the oblique walls and smooth said wingsupon said walls. I I

In the continued descentofthe presser and platen, the oblique brush Wipers 101 meet thefour horizontally projecting oblique flaps p and turn them simultaneously upward against and to adhere to the oblique walls of the box, immediately following which the combined with the inward-movement of the wing wiper mechanism, will turn and smoothly wipe said wings 29 around and upon the remaining side walls of the box. As the presser and platen continue their descent, the remaining pair of side flaps p willbe engaged by the final brush wipers 118, Figs. 4 and 15, and will be wiped upward against and to adhere to the remaining side walls of the box.

As said presser continues in its descent, the upper pressermember is arrested by contact of its stop 38*, Fig. 1, with the now stationary cam lever 47, so that the lower presser member carrying the box and platen before it, separates from the upper presser member, see Fig. 16, leaving a space into which the infolding wipers 138, by their advancing or closing movement, may turn the upstanding ends of the several covering flaps, simultaneously with the first or preliminary pressing movement of the pressers 19.8 against and to straighten the box walls.

As the pressers and infolding wipers withdraw, the descent of the cam lever 47 to position the box ejectors 45 ready to remove the box from the presser when the latter approaches its most elevated position, releases the upper presser member 35, permitting the latter to descend upon the infolded flap ends, to turn the latter downward and to press them against the inner faces of the box walls, as in Fig. 18,'whereupon the pressers 128 are given a second and final inward pressing movement to press the box walls now covered without and within, firmly against the side edge walls of the two-part presser, finally to set the covering upon the box wall Thereafter the presser rises followed by the platen, taking with them the now covered box, until the platen reaches its most elevated position, whereupon the presser leaves it and leaves the box on the platen carrying the box, being there held by the ejector rods 45, after which the box is thrown out of the machine.
